RCA Flyback Need Good Pull
Need a RCA P-N: 223011 Flyback found in CTC169RA chassis. Prefer one that
can be verified the ABL/GND Pin is in Tact and Still Connected. (This is a solder Terminal on top of the flyback) Can provide instructions and diagram on how to verify this if Need be. |

Sounds strange for that fly. All 169'ers I seen don't have this kind of solder terminal on top. Always grey lead from bottom, output for the focus/screen divider module or input lead for projector that use HV regulation. What else that comes out of topside is HV. What is that from?

RCA Flyback Need Good Pull
I can honestly say I have NEVER seen a CTC170 flyback fail, ever.
I have seen the external focus divider block fail lots of times, and it looks just like a flyback failure. Just make 100% sure it is the flyback with an external drive tester. It is also highly unlikely you will find a good used pull from that chassis. The set was so expensive that most people still pay good dollars to have them repaired. Then there was the really small production run Thomson had on the set which will even limit the possibility of used supply further. Call all the Thomsons parts distributors before giving up on a new one. David "techforce" wrote in message ... | Can't source one from RCA n or convert a correct HV fly to this config?

RCA Flyback Need Good Pull
Checked with Tritronics , who has none...checked other RCA Dist's too. None.
I have been working on this Flyback for about a year, trying to get something going because its NLA. Supplies are exhausted, as you say. The Engineer with the Last good Pull I provided says the ABL/GND connection is open. this is a Solder Terminal on top of the FBT near the tubes for anode and Screen wires. So I really need one that has this, the Secondary in Tact, so readings can be taken for engineering of a prototype. Everything else is ok. The fact that you say, its a good Set that people Like Repaired, is the reason I am trying to keep the flyback available. Its a CTC170RA, not Just a 170. I think the Last 2 Letters mean a different Flyback.
